Abstract

We study the influence of the external magnetic field, temperature, and electron concentration on the magneto-thermopower due to the phonon-drag effect, Sxxg, in the MoSe2 monolayer. The analytical expression for Sxxg is found from Π-method. Our numerical results show that the density of state and Sxxg show an oscillation as a function of a magnetic field with its amplitude increases in the large magnetic field region. The Sxxg increases with temperatures but decreases with electron concentrations. The numerical calculations for Sxxg are compared with those in the graphene monolayer.
